About This Installation Guide - Epson PowerLite 420 Installation Manual

Because the interactive module uses infrared communication, it could interfere with infrared
communication from other products. If this happens, move the other product(s) out of the detection area.
Location
•
Determine where you will install the wall mount and prepare the location in advance. Also, make sure
there is a gap of 16 to 26 inches (410 to 660 mm) from the top of the image projected onto the white
board to the ceiling. See "Positioning the Projector" on page 14 for more details.
•
Do not install the projector in a location where it might be subjected to vibration or shock. Vibration or
shock could cause damage to the projector or mounting surface. It could also cause the wall mount or
projector to fall, resulting in serious injury or death.
•
Before installing the projector, verify the power supply wiring for the installation location.
•
Install the projector away from other electric devices such as fluorescent lights or air conditioners. Some
kinds of fluorescent lights could interfere with the remote control of the projector.
•
Install the projector away from direct sunlight and other bright light sources.
•
It is recommended to keep VGA computer cable length less than 66 ft (20 meters) to reduce external
noise.
